Repairs continue on the Causeway to Granite Island with scheduled to be complete in mid-May.
The work has grounded the Horse Tram which is suspended until Department of Planning, Transport and Infrastructure engineers deem it safe for tram operations to recommence.
A City of Victor Harbor council spokesperson said the safety of visitors, staff and horses remained the number one priority.
"We would like to see the horse tram back in operation, but the long-term future of the Causeway remains at the top of our mind. On behalf of our community, we will continue to strongly advocate for the development of a new structure as the long-term solution for safe access to Granite Island," spokesperson said.
